@kbn/openapi-generator: Support object keys which need to be surrounded by quotes

[hop-dev]

Summary

❓ Are there tests for @kbn/openapi-generator? I couldn't find them ❓

Our team had a @timestamp field in an API response, this caused the zod schema to break because the key was not being escaped in the object e.g:

export const AssetCriticalityRecord =       CreateAssetCriticalityRecord.and(z.object({
      // ❌ invalid JS
      @timestamp: z.string().datetime(),
  }));

With the fix, the @timestamp key is surrounded by quotes.

export const AssetCriticalityRecord =       CreateAssetCriticalityRecord.and(z.object({
     // ✅ 
      '@timestamp': z.string().datetime(),
  }));

@hop-dev Thank you for the fix!

❓ Are there tests for @kbn/openapi-generator? I couldn't find them ❓

At this point we don't have any tests, unfortunately. Our code-generated schemas have been an excuse for that because we use them in our API endpoints, which are themselves covered with tests pretty well. We may revisit this in a few months, but currently, our team doesn't have the capacity to work on test coverage for the codegen package.
